I am 13 years old and in my vagina there's a tiny hole from which that white thing comes not discharge that white substance that comes in your teeth like that thing comes from that tiny hole and today I saw something black in that holds and then the black thing came out it was like a little circle but half circle and I see more black thing in it but can't get it out and I want to ask will it come out by its own. I am scared now I can't see the white thing properly is this okay.
